@Tes yeux noirs,
Your explanation is excellent. In basic talk ( electronics) the connection ( patch) is the result of the" male" >" female" interaction via the axon /dendrite connections
,in vitro and
in vivo.
One point to be made, is that contrary to the male/female connection observed
in vitro ( electonic connections), under the microscope with intact rat neurons
in vitro ,the synapse is very small and the action potentials that travel along the two sections ( axon/dendrite) and across the synapse, are driven biochemically via pumps regulated via Na/K flux.
The neurons were said to be "living". What should have been said, was the neurons were physiologically and metabolically functional. They weren't living .
The scientist performing these experiments has an autistic son and this supposedly is what is driving the research.
